If you are using Windows Vista or Windows 7, try running LFS as administrator before unlocking. Right click on the LFS.exe file and choose "Run as administrator"
The first "copy" of LFS I had was demo only, so I had to download the official S2 version (demo has ~350MB and S2 has like ~550MB, maybe even more) to be able to use all the cars/tracks.
Rubbish. S2 is 135MB (or in that region). Its in demo mode to begin with; you just have to unlock it (S1/S2) to use licensed content. No more additional downloads required for licensed content.
350-500 MB?! From where do you download LFS?
Of course, there are third party additions (hi-res packs, skins etc.) but you dont need those to be able to access S1/S2 content.
Dafuq? :wtf2: Once while I was a demoer I tried to play S2 (no need to explain further) and I couldn't because I had no S2 files and I'm quite sure it had more than 130MB... (E: With no skins added) But 135MB for full S2?
I think it was some site like megaupload, or some Slovenian torrent site, but it sure as hell wasn't from LFS official site, and it sure had only demo stuff in it.
